I tested 3 way calling for first time last night and it didn't work. I've had e a Pixi Plus on VZW monthly prepaid plan for over 2 years. When I go to add 2nd call, I get error message: "We're sorry, your service does not allow you to complete this call."
VZW tech tried for over half hour to help. He removed, then added 3-way, he had me remove battery (soft reset), nothing worked. He said all he can recommend is that I do a hard reset to factory state then try. If that fails, I call VZW back and have them submit a network repair ticket.
Anyone familiar with this? Could it be my phone or Verizon? I hate the thought of a hard reset. I've got a bunch of Preware aps and patches. Can that all be backed up? Ugh
